Creating and Managing VM Storage Policies

<

To create and manage storage policies for your virtual machines, you use the VM Storage Policies interface of the vSphere Web Client.

After the VM Storage Policies interface is populated with the appropriate data, you can start creating your storage policies. When you create a storage policy, you define placement and data service rules. The rules are the basic element of the VM storage policy. Within the policy, the rules are grouped in collections of rules, or rule sets.

In certain cases, you can prepackage the rules in storage policy components. The components are modular building blocks that you define in advance and can reference in multiple storage policies.

After you create the storage policy, you can edit or clone it, or delete any unused policies.

After the VM Storage Policies interface is populated with the appropriate data, you can start defining your storage policies. A basic element of a VM storage policy is a rule. Each individual rule is a statement that describes a single requirement for virtual machine storage and data services. Within the policy, rules are grouped in collections of rules. Two types of collections exist, regular rule sets and common rule sets.

A VM storage policy can include one or several reusable and interchangeable building blocks, called storage policy components. Each component describes a particular data service to be provided for the virtual machine. You can define the policy components in advance and associate them with multiple VM storage policies.

If storage requirements for virtual machines and virtual disks change, you can modify the existing storage policy. You can also create a copy of the existing VM storage policy by cloning it. While cloning, you can optionally select to customize the original storage policy.
